【考案の詳細な説明】
本考案は射出成形機或いは押出成形機（以下これらを単
に成形機という）等におけるホッパーの原料供給装置に
関するものである。[Detailed Description of the Invention] The present invention relates to a raw material supply device for a hopper in an injection molding machine or an extrusion molding machine (hereinafter simply referred to as a molding machine).
成形機に設けられている原料供給用のホッパーとして、
旋回式や昇降式等の移動方式も数多く提案されかつ使用
されているが、概して構造は複雑であり操作も難しくコ
スト的にも高いので、固定式のものが圧倒的に多く設置
されている。As a hopper for feeding raw materials installed in a molding machine,
Although many movable systems, such as swiveling and elevating systems, have been proposed and used, they are generally complex in structure, difficult to operate, and expensive, so fixed systems are overwhelmingly installed.
この固定式のものは汎用性もあり省力形でもあるが、単
なる手動操作に頼る感覚的な作業ではシリンダ内の残留
樹脂の適正な処置、例えばホッパー内材料の自動供給と
停止は困難であった。Although this fixed type is versatile and labor-saving, it is difficult to properly dispose of residual resin in the cylinder, such as automatically supplying and stopping material in the hopper, with intuitive tasks that rely on simple manual operation. .
成形機において樹脂の色替のときは、通常シリンダ内に
残留している樹脂を数ショットで空中にパージすること
により放出し、次いがホッパ内を新らしい樹脂に交換し
てから正規の運転を行っていた。When changing the color of resin in a molding machine, the resin remaining in the cylinder is usually purged into the air with several shots to release it, and then the inside of the hopper is replaced with new resin before normal operation begins. was going on.
捷た熱安定性の悪い樹脂においても、シリンダ内の性質
の劣化した樹脂はパージにより放出していた。Even in the case of broken resin with poor thermal stability, the resin with deteriorated properties inside the cylinder was released by purging.
しかしてこの作業により消費されるパージ量は成形品で
はないので全く無駄であり、かつその作業時間も損失で
ある。However, the amount of purge consumed by this work is completely wasted since the product is not a molded product, and the work time is also lost.
そしてこれらの作業は多いのでこれらの累積は膨大な量
となり、省エネルギーの点から改善が強く要望されてい
た。Since these operations are many, the cumulative amount of these tasks is enormous, and improvements have been strongly desired from the point of view of energy conservation.
本考案はかかる観点からなされたものでその目的は、従
来パージにより無駄に消費されていたシリンダ内の残留
樹脂を成形品に活用することにより、省エネルギーを可
能にした成形機におけるホッパーの原料供給装置を提供
することにある。The present invention was devised from this perspective, and its purpose is to create a raw material supply system for a hopper in a molding machine that makes it possible to save energy by utilizing the residual resin inside the cylinder, which was previously wasted due to purge, in molded products. Our goal is to provide the following.
以下本考案を一実施例を示した図について説明する。The present invention will be described below with reference to figures showing one embodiment.
成形機の加熱シリンダ１の受は入れ目２は、支持体３に
より支持されて図において左右方向に移動しかつ孔４を
有する摺動板５を介して原料樹脂１１を貯えているホッ
パー６に接している。The receptacle 2 of the heating cylinder 1 of the molding machine is supported by a support 3 and moves in the left-right direction in the figure, and is connected to a hopper 6 storing raw resin 11 via a sliding plate 5 having holes 4. are in contact with each other.
摺動板５は上記した孔４によりホンパー６内の原料樹脂
１１の流入としゃ断を行い、かつシリンダＩのピストン
８に固着されている。The sliding plate 5 blocks the inflow of the raw material resin 11 in the pumper 6 through the above-described hole 4, and is fixed to the piston 8 of the cylinder I.
シリンダＩは電磁切換弁９を介して圧力流体の供給を受
け、電磁切換弁９はプリセットカウンター１０の信号に
より制御されている。The cylinder I is supplied with pressure fluid via an electromagnetic switching valve 9, and the electromagnetic switching valve 9 is controlled by a signal from a preset counter 10.
なおシリンダＩに代るアクチェータとして、電動機とこ
れに固着したネジ軸等でもよいことはいう昔でもない。It is no longer the case that an electric motor and a screw shaft fixed to the electric motor may be used as an actuator in place of the cylinder I.
次に本考案の作用について説明する。Next, the operation of the present invention will be explained.
成形機としては予定の生産量はわかっているので、その
ときの予定量より数個（例えば 個）少い数量（以下こ
の量を予定底形品数量という）をプリセントカウンター
１０に設定しておく。Since the molding machine knows the planned production volume, it sets a quantity (hereinafter referred to as the planned bottom-shaped product quantity) that is several pieces (for example, pieces) smaller than the planned quantity at that time on the precent counter 10. put.
プリセットカウンター１０に設定した数量を成形機が成
形すると、プリセットカウンター１０は信号を電磁切換
弁９へ送る。When the molding machine molds the quantity set in the preset counter 10, the preset counter 10 sends a signal to the electromagnetic switching valve 9.
電磁切換弁９はこの信号により下方位置へ切換って圧力
流体をシリンダＩの右方室へ送り、摺動板５を左方へ移
動させてホッパー６の原料樹脂１１が加熱シリンダ１内
へ流入することを阻止する。The electromagnetic switching valve 9 is switched to the downward position by this signal to send the pressure fluid to the right chamber of the cylinder I, and the sliding plate 5 is moved to the left so that the raw resin 11 of the hopper 6 flows into the heating cylinder 1. prevent something from happening.
この状態で成形機により成形を続ければ前記した数個の
成形で加熱シリンダ１内の残留樹脂はほぼなくなり、渣
た成形機として予定の数量を成形したことになる。If molding is continued with the molding machine in this state, the remaining resin in the heating cylinder 1 will be almost completely eliminated after the above-mentioned several moldings, and the planned quantity will be molded using the molding machine.
本考案の成形機におけるホッパーの原料供給装置は前述
したように、ホッパーと加熱シリンダの間に原料樹脂の
流入およびしゃ断を行う摺動板を設け、この摺動板を常
時は開いた状態として成形を行い、成形機の予定成形品
数量を成形した時点をプリセットカウンターにより検知
し、この検知信号により摺動板を移動してホッパーかも
加熱シリンダへ原料樹脂の流入することをしゃ断させる
ように構成した。As mentioned above, the raw material supply device for the hopper in the molding machine of the present invention is provided with a sliding plate between the hopper and the heating cylinder that allows the raw resin to flow in and out, and this sliding plate is normally kept open during molding. The preset counter detects the point in time when the molding machine has molded the planned number of molded products, and the detection signal moves a sliding plate to cut off the flow of raw resin into the hopper or heating cylinder. .
従って成形機が予定量を成形すると加熱シリンダ内の残
留樹脂は殆んどなくなっているので、従来のようにパー
ジングによる無駄な樹脂の消費を大巾に削減することが
できる。Therefore, when the molding machine molds the predetermined amount, there is almost no residual resin in the heating cylinder, so the wasteful consumption of resin due to purging, which is conventional, can be greatly reduced.
また機構は極めて単純であるから広範囲の機種に適用可
能である等の多くの利点を本考案は有するものである。Furthermore, the present invention has many advantages, such as the fact that the mechanism is extremely simple and can be applied to a wide range of models.
